Except the curve you plot may have a much longer period than you seem to admit. I admit that all good things must come to an end; civilizational needs always seems to outstrip their resources. BUT the question is WHEN!

I admit that I did not generate the curve. Dr. M. King Hubbert developed the statistics based on reserves discovery that predicted the production curve - and the history of US production pretty well fell in line with his predictions. Others have extended Hubbert's work to world oil production. Their prediction is peak oil about now or in a couple of years.
